3 Claims. (Cl. 281-29) The invention relates generally to books and more particularly t9 an improved construction for securing the pages in assembled relation.

Our invention has among its objects the production of a book or booklet of the kind described, particularly adapted for pamphlets, catalogues, and the like which is simple in construction, durable, attractive, eflicient and relatively inexpensive.

Another object of the invention is the production of such a device wherein the cover is so constructed and shaped that it forms the retaining means for holding the pages in place without the use of additional mechanical bindmgs.

Another object of the invention is the production of such a device whereinthe retaining means is so shaped that the pages will readily turn on the retaining means without binding or sticking, etc.

A further object of the invention is'the production of such a device wherein a single cover forms the retaining means for the leaves which may be assembled without the use of glue or other material, the means and cover being so constructed that they interlock with one another.

Another object of the invention is the production of a book wherein the covers independently of each other pass through and secure the pages in assembled relation.

Many other objects and advantages of the invention herein shown and described will be obvious to those skilled in the art from the disclosure herein given.

To this end our invention consists in the novel construction, arrangement and combination of parts herein shown and described and more particularly pointed out in the appended claims.

Fig. 8 is a sectional view taken on the line 88 of Fig. 7; and.

Fig. 9 is a plan view similar to Fig. 6 of the cover and retaining means illustrated in Figs. 7 and 8.

Referring to the drawing,'and more particularly to Figs. 1, 2 and 3, I represents a cover formed of suitable material of a size to extend across the adjacent face of the pages '2, the latter being provided with apertures 3 therein adjacent one end of said pages, the apertures on the respective pages being similarly positioned so that they will be aligned when the pages are stacked in assembled relation as shown in Fig. 2. Extending from the end of the cover adjacent the apertures 3 are a plurality of tongues 4, the cover I being cut adjacent the tongues as shown at 5 of Fig. 3 so that the tonguesbegin at a point spaced from the edge of the cover, with the result that the lateral dimensions of the cover are substantially the same as that of the leaves. However, if desired the tongues may begin at the edge of the cover. These tongues are bent adjacent their origin transversely to the cover and extend through the apertures 3. The tongue then passes around the adjacent ends 2 of the pages 2 back to the cover I, the latter being provided with a slit 6 of a'size toreceive the end The end I is passed through the slit and extends along the inside face of cover, as shown in Figs. 2 and 3. If desired, glue 1 or other means may be employed to secure the end I of the tongue to the adjacent face of the cover although the same will be held sufiiciently l of the tongue 4.

by the frictional engagement between the tongue and cover as well as between the leaves and the ends of the tongues. construction provides a very efilcient retaining means, there being no possibility of the leaves catching or sticking. I I

If desired, the tongues 4 may be constructed to positively interlock with the cover so that glue or other means is unnecessary. Likewise while we have shown-the retaining means and cover as formed from a single sheet of material, it might,

in certain types of books, be desirable to form the cover from several different materials. A construction embodying both of these features is illustrated in Figs. 4, 5, and 6, the retaining It will be noted that this means being formed from one piece of material and the cover proper from another, with the retaining means so constructed that the free ends of the tongues will interlock with the remaining portion of the means. In the construction illustrated, the cover proper II is of approximately the same size as the leaves and secured to the cover is a piece of suitable material II from which the tongues l4 are formed. This construction would be advantageous, for example, when the cover proper II is to be formed from relatively stiif material, whereby said cover could be formed from such material and the portion carrying the tongues could be formed from more pliable material, this providing a cover and retaining means, as a unitary structure, in which both the cover proper and the retaining means are formed out of materials most suitable for each. As shown in Fig. 6, the tongues H are provided with two slits l5 and IS, the slit l5 being positioned on one side of the respective tongue, intermediate theends thereof, and as shown, extending approximately half way through the tongue itself, the slit |6 being positioned on the side of the tongue opposite the slit l5. Obviously, the exact size and positions of the slits will depend upon the relative proportions of the tongues used, and the size of the loop, formed by the tongues, desired. As shown in Fig. 5 the tongues H are passed through the apertures 3 in the leaves 2 and cover 9 as in the other constructions and passed around the ends 2' of the leaves, after which the portions l8 are.

sprung slightly to allow the end of the tongue II to engage the slit I6, adjacent the slit IS on the tongue, as shown in Fig. 4, thereby interlocking the tongues with the portion II and therefore with the cover The construction shown in Figs. 7, 8, and 9 is somewhat similar to that just described, but provides a more positive locking action. As shown in Figs. 7, 8 and 9, particularly Fig. 9, the cover 2| is provided with tongues 24, the tongues being provided with slits 25 corresponding to the slits i5. However, the slits 25 are spaced from the sides of the tongue and a smaller secondary tongue 29 is cut from a portion of the tongue 24 intermediate the slit 25 and one edge of the tongue 24. A second slit 26 corresponding with the slit I6 is also provided adjacent the juncture of the tongue 24 and the cover 2|. It will be noted that the slit 30 severing the tongue 24 from the portion 28 of the cover 2| intersects the slit 26 intermediate the ends of the latter, so that the width of the tongue decreases from the outer edge of the portion 28 toward the slit 26. Thus when the tongue is brought through the leaves around the ends of the pages and back to the cover similarly to the tongues l4, and the tongue is engaged with the notch 26 adjacent the notch 25, the portion 26 adjacent the slits 26 and 30 will overlap the edge of the tongue as shown at 3| in Fig. 7.

Referring to Figs. 7 and 8, it will be noted that the small secondary tongue 29 is positioned adjacent the inner end of the tongue 24 while the extreme outer end 21 of the tongue is positioned adjacent the inner face of the cover 2|. As the tongue 29 overlaps the inner portion of the tongue 24 adjacent the cover and extends through the apertures 3 in the leaves 2, the latter will tend to press the tongu 29 against the tongue 24 thereby providing added frictional engagement between the parts and lessening the strain on the locking means.

It will be noted from the above description that we have provided a book in which the cover or covers provide the retaining means for maintaining the leaves in assembled relation, wherein said means is so constructed that the individual leaves will at all times freely turn thereon without binding or sticking. While the covers carrying the retaining means have been illustrated as substantially coextensive with the leaves, obviously, the cover may be longer or smaller than the leaves as desired. Likewise, we have provided novel means for interlocking the retaining elements in position without the use of glue or other additional material.

Having thus described our invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit of our invention; hence, we do not wish to be understood as limiting ourselves to the exact form, construction, arrangement and combination of parts herein shown and described or uses mentioned.
